Which of the follwing characteristies of electrons determines the current in a conductor?

Options

A. drift velocity alone
B. thermal velocity alone
C. both drift velocity and thermal velocity
D. neither drift nor thermal velocity

Explanation

The relationship between current and drift speed is given by
`I=n eAv_(d)`
Here `I` is the curret and `v_(d)` is the drift velocity. So, `IpropV_(d)` Thus, only drift velocity determines the current conductor.
